Respuesta :
y=5x is proportional.
when you plot it on a graph, the ordered pairs are
(0,0) (1,5) (2,10) (3,15).....
which is proportional
Y=5x could and could not be proportional depending on how the graph is plotted so if it is (5,25)(6, 30) Than that is proportional but if it is (5,34) And (6,31)Than it is not proportional. I hope this helped :)
